Leica IIIa, manufactured in 1939 with a serial number in the 330,000 range. A Barnack Leica from the sheet-metal era, coded AGNOO by Leitz. This example features the larger tripod thread. The IIIa, which added a 1/1000-second shutter speed to the DIII, was reportedly popular among sports photographers of its time.
While black-paint finishes had dominated earlier DIII models, the IIIa marked the beginning of chrome plating as the new standard for Barnack Leicas. Features introduced with the Leica DIII—strap lugs, diopter adjustment, and a slow-speed shutter—were all retained, making it a highly practical Barnack model even today.
Compact lenses such as the collapsible Elmar or Elmar 35 mm complement it beautifully, allowing it to slip easily into a pocket. Unlike the later die-cast IIIc and beyond, this model offers the delightfully smooth, hand-fitted feel characteristic of the earlier sheet-metal Leicas.

This is one of our previously sold items that has now returned to us after being carefully used by its owner.
There is a fine scratch on the base plate and some light signs of use such as minor rubbing, but for a Leica IIIa—models that are usually well worn—this example is in remarkably fine condition. There are no dents or impact marks. The sharply defined edges of the body and the beautiful chrome finish on the top cover and dials clearly convey the exceptional craftsmanship of Leica during its pre-war golden era. The original vulcanite covering is intact and provides a pleasantly smooth grip.
Overhauled in 2023, it remains in excellent mechanical condition thanks to meticulous servicing. Operation of all controls is smooth, and the viewfinder offers a bright and clear image.
